Fans are rooting for Jessica Jones Season 2, scheduled for a 2018 release, and are probably waiting for Kilgrave to return. However, the fan-favorite Purple Man is going to be absent. Showrunner Melissa Rosenberg explains to Entertainment Weekly why Kilgrave will not appear in Jessica Jones Season 2.

She points out that his performance in Season 1 was unique, and should stay that way. Repeating what they did in Season 1 would ruin the greatness of David Tennant’s performance as Kilgrave, as well as the story.

Asked about the antagonist in Season 2, Rosenberg replied that there will be more, but different from Kilgrave:

Or antagonists, plural. No one is ever going to beat David Tennant as Kilgrave, so you don't do that. The biggest mistake would be to try to repeat that. You just go, “OK, we're not doing that, so we have this open to us.”

Jessica Jones Season 2 will focus more on relationships

It seems that one of the main themes that Rosenberg wants to explore in Season 2 has more to do with the partnership between Jessica and Trish. She talks about their history and friendship, but I guess Trish will become a kind of Jessica Jones sidekick. Rosenberg confirms that she doesn’t want to explore a romantic relationship between the two of them, and what else could we expect from a friendship between a superhero and her best friend? My guess is that Trish will be Jessica’s ally in fighting against new villains. Rosenberg continues about exploring relationships as a main theme for Jessica Jones Season 2:

I'm interested in continuing to explore the relationship between Trish and Jessica. That is the core relationship in the piece. It is about female friendship, it is about how friends evolve "” they're sisters, really "” and it's about how they evolve and ping off each other. I'm interested in relationships, whether they be romantic, or family, or friends, or professional "” that's what's interesting to me, is Jessica in relationship to people.
